sounds ok to me also..RR, knows his stuff having had many similar dreams, pardon me RR, for not mentioning this,,in fact I know you "know More about" this particular Rxn than I--as that Man says terror, you'll be fine. I'm sorry If I came off somehow, as "more knowledgeable" than the RageR .......terror just coz I have 'More posts means Nada' and that goes for almost everyone here almost, but for the top 10 or so High numbered posters, and with time you will see we Often have Different Types of Dreams, If you know what I mean, in fact,, probably some of the "so called Newbies" on THIS forum, ARE in Fact, some of the smartest,people here, So Dont Be Fooled by the BIG Numbas, And whats more, I WILL ONLY SAY, what I KNOW to be OK or I would tell you that " I wasn't sure, and that maybe you should ask so n so or somewhere esle in the forum",,If you think I can help,please,still feel free to ask

As Far as I an concerned, this Is a Place to "Share the Love" so dont be shy if you need an idea or hint

None of us Need OR Want to get stuffed around with-I realized I had given you a "poor quality answer", and it Needed Improvement, AFTER RR posted below, and I saw the "mistake" i had made, for want of a better word! posting a "too simple" YES, yeah I know it sound funny, but if you ever get into "Cognitive Behavioral Psychology" you'll understand it easier...maybe,maybe not sorry, I was in a hurry and should have waited (PATIENCE) before rushing that off while you're sitting with a bottle full of juicy p2p,,I can be a thoughtless fuckwit at times!!!

take is slowly you'll do fine "haste makes waste" More than almost ANYTHING in Organic, and other chemistry, as well as Life , in general, Patience IS a Virtue, in this game as it Also IS in Life Too

What the most feasible method for the home hack such as myself to prepare concentrated HCl starting with muriatic acid? I know distillation is out of the question, but maybe some other method of dehydration might work. I have read about bubbling HCl gas through as well. At what percentage is the solution considered to be 'concentrated'? Are there any ways to check the percentage? Titration? How do some of you titrate?

I've already blown one experiment were I substituted concentrated for muriatic (iirc 37% but not sure) and the result were so far from what I expected there is no doubt that muriatic is not strong enough.

"Specific Heats" aka Specific Energy 1.72 (kJ/kg.K) Not sure if this is exactly what you are looking for, as in I'm unsure about "Combustion".

Does anyone have a good paper on the decomposition of oxalic acid? It decomposes when used to reduce imines (eschweiler-clark), when used to in the beckmann rearrangement, and apparently during the preparation of hydroxylamine from a nitroalkane. I've always wonder about it's utility in the Lossen..

what about these? hxxp://www.oecd-nea.org/trw/docs/mol98/postersession/POSTSpaper10.pdfand hxxp://pubs.acs.org/doi/abs/10.1021/j100789a032 ?

Although both are primarily about gaseous phase kinetics of these compounds, they are quite interesting, and the second paper, Does suggest, that this is to discern their behaviour in various states---at the very least, there are the references, They used!!!

I Hope they are of some assistance/help, enkidu

What's it mean when they say O-methyl so and so? It sounds as if there is a methyl group attached to an oxygen or perhaps an oxygen is exchanged for a methyl group, but that doesn't match the pictures that are beside the places where I'm reading O-methyl.

You're right. O-methylation means there is a methyl group attached to an oxygen (methoxy group).

Perhaps the context of what I was reading at the time would help.

From "The chemistry of Hydroxylamines, Oximes and Hydroxamic Acids"6. Synthesis of oximes and hydroxamic acids[/b]

Quote

In 2002, Kanno and Taylor30 successfully developed a simple one-pot procedure usingMnO2 /NH2 OMežHCl for the conversion of activated primary alcohols into O-methyloximes (Scheme 11).

This caught my attention because monomethylation has been of interest lately. I wasn't sure if this somehow meant I could add a methyl to an oxime where I wanted it to be on the finished compound, mostly in the 5th ring position since the 5-Meo interests the shit out of me. The drawings did not show a methyl attached to any oxygen, so I was holding on to the hope that maybe this was something I was looking for.

I undestand what you says, but from what I understand, you would still have to find a way to O-methylate your hydroxylamine as they're producing the O-methylated oxime with methoxyamine hydrochloride( O-methylhydroxylamine hcl).

What would happen if one tried a sandmeyer reaction on tryptamine? Which nitrogen would be affected? Would protecting the indolic nitrogen avoid its reactivity?
